|Mars Orbiter Helps Scientists "Follow the Water"|
Five years ago, NASA's Mars Reconnaissance Orbiter was launched in search of evidence that water persisted on the surface of Mars over a prolonged period of time. Previous Mars missions indicated that, at some point in the Red Planet's history, water flowed across its surface. Throughout the years, MRO has continued to analyze minerals, look for water, trace the distribution of dust in the atmosphere and monitor Martian weather.

|NASA's MRO Sees Possible Martian Water Flows|
Observations from NASA's Mars Reconnaissance Orbiter, MRO, have revealed possible flowing water during the warmest months on Mars. Scientists discuss the findings at a NASA Headquarters news briefing held August 4, 2011. Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle l...

|"Opportunity" to Spend 7th Anniversary at Stadium-size Crater|
The Mars Exploration Rover Opportunity has been photographed beside a 100-meter-diameter Martian crater by the high-resolution camera on NASA's Mars Reconnaissance Orbiter. Opportunity will explore the Santa Maria crater over the next several weeks. January serves as an important milestone for Opportunity and its twin, Spirit: This month, both rovers are celebrating their seventh anniversaries on Mars.

|Martian Holiday- "I'm Dreaming of a Blue Sunset"|
Two new movie clips from Mars give us a rover's-eye view of a bluish Martian sunset and the silhouette of the moon Phobos passing in front of the sun. NASA's Mars Exploration Rover Opportunity, carefully guided by researchers with an artistic sense, has recorded images used in the simulated movies.
